What is the best way to send music

I have 6 full CD's of original music tracks and I want to send them to a friend in Nigeria. Obviously I can copy the CDs and send them by post but the postal service in Nigeria is very unreliable I'm told.
I could attach to a series of emails but it would take several. Is there a way of sending the tracks electronically & easily?

I've installed Dropbox & zipped a folder containing all the music files into the dropbox folder - its nearly 500,000kb.
Dropboc is uploading the file - it tells me it will take 17hours at 34.9Kb/sec.
I'll leave it running and see what happens!
I'm not sure that this is a practical solution.

The folder of mp3 tracks is 484MB. I zipped it to get the dropbox file of 471MB - just a slight reduction but the dropbox instructions said it had to be a single zip file. There are about 100 music files.
I left it running so I don't know how long it took eventually. I'll get to the rest tommorrow.

All you needed to have done was create a folder in your DropBox and copy your tracks into it which should only have taken a few minutes you can then share that folder with anyone you want and they do not need to have DropBox installed .

After a mobo upgrade at the weekend and reinstalling Windows I also reinstalled DropBox and the 2GB contents took less than half an hour to sync so am really puzzled as to your figures.
